application filed February 21, 191?. Serial No. 150,289.

To all "whom it may concern:

Be it known that ll, GEORGE lF. Minnie, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in WindowWVashers Safety Devices, of which the following is a specification.

This invention relates to improvements in separable fasteners, and more particularly to an anchored fastener and rope carrying clip for engagement with the fastener such as is used by window cleaners as a safety device when working outside of a building.

One of the objects of my invention is to provide an improved anchoring means for such a device.

Another object of my invention is to pro- :vide a rope attaching device which may be easily and quickly adjusted by one hand to different places on the rope.

A further object is to generally improve devices of this nature to increase their eff: eiency, ease of operation, decrease the liability to breakage and increase the facility with which they may be operated.

Still other and further objects will become readily apparent to those skilled in the art from a consideration of the following description. and drawings, wherein-- Figure 1. is a vertical sectional view through a portion of a wall illustrating the manner of in ounting my improved fastening device thereon. a

Fig. 2 is a plan view illustrating the method of attachment to a wall. i

Fig. 3 is a vertical central sectional view through the clip showing a portion of the anchor in side elevation.

Fig. 4 is a front elevation.

Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 1 and;

Fig. 6 is a perspective View of the end of the anchor and the clip detached.

Fig. 7 is a perspective view of the rear side ofthelclip. j

Referring to the drawings, wherein l[ have illustrated a preferred embodiment of my invention the numeral 10 indicates an elongated base member from the upper front portion of which projects a squared neck 11, enlarged at its end to provide a squared head 12. At the lower portion of the base if have provided an outwardly extending rectangular neck 13 provided with a rectangular head 14, the neck 13 and head 14: being vertically elongated, but of a width equal to the width of the neck and head at the upper end of the base. The baselO. is adapted to lie against the outer. face of a wall and is held in place by means of an anchoring device extending rearwardly for engagement with the brick wall. This an-, chorinp; device in my preferred embodiment takes the form of a rectangular frame comprising upper and lower bars 15 and 16, an end bar 17 and a front bar 18, the latter being formed integral with the face 10. This anchoring frame is of a size approximately equal to the cross section of a brick and its thickness is approximately equal to the mortar space between adjacent bricks so that the same may be positionedbetwecn the ends of two bricks 19, 20. and embedded in the mortar connecting their ends.

Lugs 21 project outwardly from the and bar 17 of the frame at both the top and bottom thereof and at opposite sides to engage the rear faces of the bricks l9 and 20 and to lie within the mortar joining the front tier of bricks with the second tier of bricks at the rear thereof. lln order to provide a posi tive and efficient anchoring means for preventing the fastener from being pulled out and not dependent upon the outer tier of bricks alone if have provided in addition to the above described anchor an extension 22 which projects rearwardly from the bottom bar 16 of the rectangle and is flattened out horizontally to lie between the brick 23 um derlyinp; the abutting ends of bricks l9 and 20 and the brick 24L which is positioned directly at the rear of the bricks 19 and 20. This bar 22 is headed at its end 25 to pro vide prongs extending upwardly and downwardly into the mortar joining the rear faces of bricks 23, 24 with those positioned nextat the rear thereof. The arm 22 is therefore overlain by bricks 24 resisting any tendency to upward movement due to down pull on the base and additionally securing the fastoner by anchoring into the second course as well as the first.

My improved clip for engaging the heads 12 and 14 comprises a body part 26 with a bottom section 27 extending outwardly and. downwardly from the body 26. Between the bottom sections or side walls 26-26 and 27-27 is a slot 28,.wide enough at its rear end to admit the heads 12 and 14B of the projections, see Figs. 3 and 4. It is only wide enough at its front end to admit the necks 11 and 13, respectively, of the projections.

The body portion 26 is vertically slotted, as at 28, the slot opening to the lower end of the body and'terminating at a point near the upper end.- The thickness of the body part 26 is tapered from top to bottom, being at its upper end somewhat less than the length of the neck 11 of the fastener and at its lower end approximately equal to the combined length of the neck 13 and head 14. The upper end of the body part 26 is hooked over as at 29 to overlie the head 12 and serve as a stop for a flat leaf spring 30 riveted as at 31 near the lower end of the body part with its upper end pressed inwardly against the clip. The upper end of the spring terminates at a point sufficiently below the upper end of the slot for engage-- ment with the lower side of the head 12 when the clip is in position thus serving as 'a lock to prevent unintentional removal of the clip, a handle or knob 32 being provided at a point approximately midway its ends for engagement by the operators fingers, thus permitting the spring to be pulled outwardly until it will pass over the end of the head 12 in the operation of sliding the clip upwardly and over'the fasteners.

The lower end of the extension 27 is formed into a rope engaging member whichcomprises' two cylindrical thimbles or tubes 33, 34, the upper lying with its axis extending horizontally from right to left, and the lowerpositioned directly thereunder with its axisat right angles to the axis of the first and'extending horizontallyfrom front to" back, the axial centers of the tubes being in vertical alinement. A rope section passed through the thimbles 33, 34:, in the manner illustrated in Fig. 1 is securely locked in place. One course 35 of the rope extends from front to back through the bottom thimble 34L and is then brought upwardly and extends through the upper thimble 33 from left to right, the end being brought down and under the course 35, as at 36. WVith a hitch of this character it is possible to lengthen or shorten the rope without using both hands. The section 35 is pushed back through the lower thimble and the slack thus formed between the two eyes is taken up by pulling on the upper section 35. In lengthening the rope the operation is reversed.

mereas I have illustrated and described a single embodiment of my invention it will be obvious that many changes may be made therein without departing from; the spirit thereof or the scope of the appended claims.

Copies of this patent may be "obtained for Having described my invention what I claim is 1. An anchoring device for attachment to a brick wall comprising a vertically disposed elongated base to overlie the face of the wall, spaced apart heads projecting outwardly from the upper and lower portions of the base, an anchor frame of a height approximately equal to the thickness of a brick and of a length approximately equal to the depth of a brick projecting rearwardly from the base for inclusion between the vertical end faces of adjacent bricks, and a bar integral with the frame and extending rearwardly to lie between the horizontal faces of adjacent bricks at the rear of the frame.

2. An anchoring device for attachment to a brick wall comprising a vertically disposed elongated base to overlie the face of the wall, spaced apart heads projecting outwardly from the upper and lower portions of the base, an anchor frame of a height approximately equal to the thickness of a brick and of a length approximately equal to the depth of a brick projecting rearwardly from the base for inclusion between the vertical end faces of adjacent bricks, anchor lugs projecting from the rear of the frame at right angles thereto, a bar integral with the frame and extending rear.- wardly to lie between the horizontal faces of adjacent bricks at the rear of the frame, and anchor lugs projecting from the rear end of the bar at right angles thereto.

3. An anchoring device forattachnient to a brick wall and-for cooperation with a slotted fastener, comprising a base to overlie the face of the wall, an anchoring extension proj ecting rearwardly therefrom, a neck headed at its outer end projecting from the upper end of the base, and a second headed neck projecting from the lower portion of the base and of a vertical dimension considerably greater than the first.

4. An anchoring device for attachment to a brick wall, comprising a vertically disposed, elongated base to overlie the face of the wall, spaced apart heads projecting outwardly from the upper and lower portions of the base, an anchor frame of a height approximately equal to the thickness of a brick and of a length approximately equal to the depth of a brick projecting rearwardly from the base for inclusion between the vertical end faces of adjacent bricks, and anchor lugs projecting from the rear of the frame at right angles thereto.

In testimony whereof I hereunto set my hand.

GEORGE F. MINNIS.
